Glenn Quagmire, who mostly goes by his last name, is one of the Griffins' neighbors on Family Guy. Quagmire is a bit of a lovable perv and is voiced by the show's creator, Seth McFarlane.
Though you could never tell by the way he acts, Glenn is actually an airline pilot. Oh and Quagmire has a huge thing for Lois and ruined Cleveland's marriage. I say don't leave him alone with your daughter or wife.
Quagmire: Are we supposed to laugh at that? Because it's upsetting.
